I know Dave does some good stuff, but here is another local shop in Santa Clara that does amazing work as well. http://www.replikamaschinen.com. They also do all of their own flow bench work in house. I just had my head done by Don Redmon and it flows like a hurricane. I can't believe the CFM he got out of my B16 head and all of the ports match within a 1/10 of a cc. Flow benching in critical to get the same amount of combustion across all 4 cylinders. I picked up 27 HP from porting and flow benching alone. That was before the full valve train and cam work. He also offers a full line of thermal coating. Check out his website, you will be impressed.

how much did replika cost? and how long was the wait

Replika is pricey but well worth the wait and the results. My head took about three weeks to complete. Porting took about 15 hours and it spent 35 hours on the flow bench fine tuning each port to match the others. The basic head package for a 4 cylinder engine starts at $995 and goes up to $3000 depending on how wild you want to get. Call Don at Replika Maschinen if you have any questions on pricing at 408-986-8626. Please let me know if you have any other questions on my head.

how much did you end up spending to achieve those type of results? because 27HP sound very nice to me!

I went all out. I chose the stage 3 package and added the stanless valves, titanium retainers, double valve springs, full port reconstruction and port mapping, stock cams with a custom grind including a cryo treatment for hardening, multi-angle valve cut and a full line of thermal coating including the outside surface, combustion chamber, intake ports, exhaust ports, and valve heads for a price of $3,100. Pricey, I know, but worth every penny when you are trying to squeeze every last drop of power out of a honda motor.

Replika is one of the best in California. They have over 30 years experience. It's better to spend a little more money and have it done right. Here is more info on them.

how much power are you putting out with that setup and have you timed it yet?

It has yet to go on the dyno but an educated guess would be right around 300 HP at 10 pounds of boost. Since this car is no longer set up for drag it wont be hitting any straight aways any time soon. It was built more for course racing. Again, an educated guess on 1/4 mile times would be right around 12.9's. This is all estimated though.
